Reprocessing of UNF that has been out of the reactor for less than about 50 y requires the removal of ⁸⁵Kr from the process off-gas streams. This is needed despite the relatively small amount of that isotope in the combined Xe and Kr inventory (Table 1). The decay of ⁸⁵Kr to ⁸⁵Rb presents challenges to the materials that will potentially be used to remove and store the Kr recovered from the off-gas. To address some of these problems, a thorough literature survey was completed, and the results of that analysis are summarized in this document.
